Well, this was one of the more interesting trouble shooting events I've had in a while.
Believe it or not, it was the alternator.... For some unknown reason, perhaps an indication of pure desperation, I disconnected the main wire to the alternator, and it ran perfect (asides from the battery light coming on)
All I can imagine is one of the rectifiers in the alternator went out six months ago, and the resulting 'noisy' output was confusing the poor computer..
With the new alternator she's running good again, but now there is a new problem. Rear brake sprung a leak somewhere on top of the gas tank. (Its always something.....)
Anyway, thanks again for the advice
Take Care, James Lerch
